The project aims to determine the mechanisms that govern melting of Antarctic ice shelves into the ocean. Faster basal melting of ice shelves in the warming ocean is contributing to loss of grounded ice from Antarctica and increased glacier speeds, and melting is projected to become a larger contribution to future global sea level rise. Using unique laboratory experiments, turbulence-resolving computation and theoretical analysis the project will evaluate the roles of meltwater, ocean currents, internal wave breaking and water exchanges between the continental shelf and sub-ice cavities. The results will assist our understanding of measurements made in Antarctica and more reliable predictions of sea level rise.

该项目旨在确定控制南极冰架融化进入海洋的机制。海洋变暖导致冰架底部融化速度加快，导致南极洲地面冰的流失和冰川速度的加快，预计融化将对未来全球海平面上升产生更大的影响。该项目将利用独特的实验室实验、湍流解析计算和理论分析来评估融水、洋流、内波破碎以及大陆架和冰下腔之间的水交换的作用。结果将有助于我们了解在南极洲进行的测量以及更可靠地预测海平面上升。
